when my buddy rebuilt the tranny for me he noted that the transfer case was slightly low and that it looked like the vent tube had been burping some. he then measured the circumference of my tires an saw that there was about a 3/4 in difference between the front and back tires( i had not rotated them in a while and the backs had wore down more). he informed me that the different rotation rates of the tires would cause the the transfer case to slip some to account for the different wheel speeds. this causes the transfer case fluid to heat up and vent out the overflow tube. told me I needed to get new tires before i tried to drive it from Mich to NY.
I have not seen the leak since the new tire went on and I am just getting ready to turn over 250,000 miles.
this truck has been verrry good to me!!!!!

It has been a great vehicle from me. It less than 500 miles from turning over 250,000 miles. Mostly highway and more than half of those miles with northern lite camper on the back. Still on the original exhaust system (kind of blows me away).
the minor problem is that the "in the mirror" compass and temp gauge will sometimes blink off for a few seconds then turn back on all the letter segments then start working correctly. but it only seems to do this while the intermittent windshield wipers are operating. Once the wipers sweep across the to the passenger side and start back the compass/temp gauge blink off. this is not a major problem just an annoyance. makes me wonder what else is about to fail.
anyone seen this one before?
The major problem is that I have been experiencing a drop in engine rpms sometimes when I switch from reverse to forward or from forward to reverse. sometimes the engine stalls, but restarts right up. it seems to happen more often when the engine is cold but is not limited to a cold engine.
Related to this but maybe not the same problem is that two days ago while in the highway at 70mph and climbing a long hill the transmission down shifted to 3rd and seem to lose power and lugg. At the top of the hill if seemed to regain full power and was fine up the next hill. but on the third hill it repeated the same problems. I was able to pull over in a rest area where it stalled out completely and would not start up and run at all for about 20 minutes. no idiot lights or warning ever came on. It then would start but was very rough running and would not rev higher than 1000 RPM. I let it sit for a while while I checked the plug wires, smelled the tranny fluid and the oil and unplugged and reseated as many connectors under the hood as I could find, (thinking that I may have an intermittent connection somewhere). The tranny fluid and oil did not smell burnt so I do not think it was overheating in the engine or transmission. After about a 25 minute rest it start right up and seems to run fine I kept the speed at or under 55 from then on and have not had a repeat. outside temp was 71 f. so not real hot day.
at this point this old truck does not owe me anything but the body, frame and transmission are in great shape engine burns a little oil and has a pronounced piston slap when cold, but I still want to keep her running and try for 500,000.
does any one have any ideas as to what is up with this ?
thank Jerry :confuse:
As to the minor issue of the in mirror compass / temp guage acting up, I'm not certain about this because you have sort of tied your truck's misbehavior to the operation of the windshield wipers, but it surely can't hurt to check. My 2004 had intermittent problems with the same situation but not limited to during windshield wiper operation. Turns out that the connector on the back of the mirror that the wiring harness goes to isn't all that snug fitting, and I had worked it a bit out when using some sunshades over the dash. Just minor vibrations going down the road was causing the problem. Once I realized what the issue was and reseated the plug, everything was fine again.
Oh, congrats on making the 250k+ mark. And I hope you do make the 500k mark. These trucks may have some issues from time to time, but overall they're fairly reliable beasts.
Also, I have the erratic fuel gage as well. What's weird is that when it's not registering correctly, all I have to do is take it from Drive to Park, and it will register correctly... for a while. Any thoughts or ideas? I've caught wind of a potential grounding problem. Does anyone had any insight on that?
I would check the exposed wiring loom in the door jamb
then pull off the door panel.
Prob. a pinched or frayed wire somewhere
I have a 2001 chevy silverado 1500, 5.3 v8. And for the last weeks, i have been driving with my "service engine soon" light on. I had borrowed one of my colleage's diagnostic scanner to pin point the problem and this is what it said: P1415 - air system bank 1 and P1509 - IAC system high RPM. Could any one tell me what the heck does this mean??? I talked to and couple of people and they said it could be my O2 sensor and or the idle air control unit.... Please help me answer my questions, your technical experience would likely be appreciated, thanks!!!!!
call the Chevy 800# and have your VIN# handy.
You may be in line for the FREE recall even tho
you haven't been notified yet !
NOTE: That GM will also give you any recalls that
your truck needs and were never done or you were
not notified of......................
Had the wheel off, but do not see anything out of norm.
Any ideas before callling in the dealer?

thanks
on the major problem I did find out that the fuel pump was on its way out, it failed completely and left me stranded on the road. I got that replaced but I am still experiencing the inconsistant idle when switching gears. so I am betting that one if the engine sensors is out of commission intermittantly. I just don't know how to figure out which one it is.

new PCV valve
Ok, well my heat and Ac works good temperature wise, my vent is on defrost and wont go to floor or vents, i checked the control box its ok, i checked the actuator up inside the dash passenger side, you have to dam near take the whole dash off to see it its way up there crappy location! its works and moves, now when i got this truck is had been trough alot of mud I coul dtell, is it possible its something underneath the truck thats causing this to default? THANKS GUYS!

Here's a probable solution to your dilemma with the blower. Check your owners manual first and get oriented. You have an interior cab filter under the dash on the passenger side. They get plugged up pretty fast if your off the asphalt much. They get plugged up anyway! Your blower is probably just fine but it can't push air that it does not have. When you install them make sure that they are in correctly. The filter should have an arrow showing air flow. Good luck. This is a much less expensive solution.

Problem:
When it is even slightly cool or wet outside it doesn't want to start. It turns over and after about 10 minutes of cranking it, it finally starts. I also noticed a whining sound when cranking it. :confuse:
Once its running, there is hesitation for the first 5 minutes of driving. I had the hesitation problem before the not wanting to start problem began.
If it has been running and is shut off, it will start right back up no problem.
I have changed the plugs,wires,rotor, and cap. I have also changed the fuel filter.
Anyone that might have any ideas as to the problem or if you have experienced the same thing, please let me know.
Good Luck....

Half ton, LS, 5.3, extended cab.
And I got 21mpg on the hwy doing 65mph on my last road trip (empty truck, not towing of course).
Glad I didn't buy a long bed:)
The only other time it needed to visit the dealership other than routine maintenance was to replace the tailgate cables. Overall a very pleasing ownership experience.
BTW, nice mileage results! My best was 21.7, but my routine mileage averaged in the 19s. :P
when defrost or recirc. mode is selected to dehumidify the air.
If thats your issue.............
My 04 and 01 did the same thing.
geo9.... thanks for the fast response
set to cold. If you slide it to hot it will be hot air
coming out of the vents.
The AC comp. should only kick in if the fan is on (but
I should recheck my operation just in case).
Otherwise air will always blow out of the vents if truck
is moving. With these GM HVAC systems you can never
really shut the air flow off.
Remember the old GM "astro ventilation" from the late 60s
early 70s? Always fresh air flowing thru the vehicle.
The reason this seams odd to me is because there are times when I find myself in a lot of dust or just bad air (black diesel fumes in front) and in my delta I just switch to recirculating and wait it out. No air-conditioned cold air involved unless I choose it.
Any Way thanks for the help.
